The tutorials below illustrate several applications of GIS. These tutorials are based on the use of the free and open source software QGIS which can be downloaded here. Different data sources useful for making maps will also be presented.
Getting started with vectors processing
This tutorial shows the basics of vector manipulation with QGIS (add vector layer, make a map based on a variable, add new variable to attribute table…)
Data source: IGN BD TOPO
Combine vector layers
After having seen the basics of vector manipulation with QGIS, we will now see how the different layers can be combined.
